At A Glance: DevExpress
The world we live in is constantly producing computer software and programs that are input-intensive. As the development of software becomes increasingly complex, so does the desire for simpler and more visually interactive software interfaces. DevExpress is a company founded in 1998 that offers a variety of software for UI control. UI controls are graphical interfaces, such as buttons, scroll bars, or other graphical elements, that a user can interact with directly to input parameters into the software. DevExpress offers programs that focus on products and users of the Delphi/C++ programming languages. A DevExpress specialist is the ideal solution to implementing UI controls in any project.
A DevExpress specialist is a professional who is fluent in all DevExpress projects and can help you or your business implement widgets or UI controls into a variety of software and projects. A DevExpress expert is generally well-versed in the software or framework he or she is working with or modifying, including programming protocols such as .NET, Microsoft Silverlight, and many others. In addition to various software and computer skills, DevExpress professionals possess a general knowledge and experience in GUI design as well. The variety of projects that the DevExpress software intersects with gives those users who are familiar with their products a unique set of experiences that can help them brainstorm innovative solutions to a wide set of problems. The dynamic skill set a DevExpress specialist brings to the table can be a valuable addition to any business’ or organization’s project.
